CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 15, 1916.

Application filed October 6, 1914. Serial No. 865,234.

T 0 all whom it may concern:

Be it known that I, RALPH V. SAGE, a citizen of the United States, residing in the city of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Car Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it make and use the same.

My invention relates to steel car underframes with special reference to the center sills and body bolsters thereof, and it consists in the construction of the center sill, the draft sills and body bolsters.

Heretofore in railway car construction it A has been a difficult matter to so construct the oint between the draft sills, the bolster and the center sills, as to provide an efficient transfer of stress from the draft sills through the bolster to the center sills. Failure at said joint very often takes place in the common forms of construction and if complete failure does not occur it is very frequently necessary to repair or replace the connecting members ofthe draft sills, bolsters and center sills. I am aware that several forms of joints forthe said members have been constructed, but the cost of such construction has been thereby greatly increased and an additional number of parts have been made necessary by a cumbersome construction.

It is the object of my invention to provide an efiicient draft sill, bolster and center sill connection that can be economically and simply constructed.

Since the details of construction of both ends of an underframe are substantially identical, only one end has been illustrated in the accompanying drawings, and the description of the parts here shown will enable others skilled in the art to which my invention pertains to make and use the same.

Referring now to the accompanying drawing in which like reference letters indicate like parts throughout the several figures: Figure l is a top plan view embodying my invention; Fig. 2 is a sectional elevation on the line II-II of Fig. 1, Fig. 3 is a sectional elevation on the line IIIIII of Fig. 2; Fig. 4 is an elevation of the end of either a channel or I-beam center sill with a portion of the web removed; Fig. 5 is a cross section on appertains to the line VV of Fig. 4 and shows a channel shaped center sill.

In order to reduce the depth of the center sills 1, perforations 2 are either punched or drilled in the webs thereof at some distance from the bolster and the portions 3 of the web are removed by any desirable means. The end flanges 4 are then forced together until the portions 3 have been closed, when the said flanges will still be parallel to the top of the center sill and equal to the depth of the channel bolster members 5 and 6 at their inner ends.

Dished diaphragms 7 are disposed between the webs of the center sills at the bolster and act as braces therefor. At a short distance in front of bolster the ends of the center sills abut against the draft sills 8 which are of the same depth as the ends of the said center sills. The ends of the channel bolster members 6 are bent at right angles, reduced in depth and so formed into brackets 9 as to fit snugly against the webs and flanges of the center sills and the draft sills at their union and adapted to be diveted to, and to securely splice, the said members.

ivets pass through the bent ends of the webs of the channel bolster members 5 and 6, the vertically extending flanges ofthe dished diaphragms, and the webs of the center sills, thegeby securely fastening said members toget er.

A plate 10 extends along the lower flanges of the bolster, beneath the center sills and is adapted-to be riveted to the bottom flanges of the channel bolster members 5 and 6 to the bottom flanges of the center sills and to the bottom flanges of the dished diaphragms. A perforation 11 is formed in the central portion of this plate for the reception of the king pin.

Floor plates 12 extend laterally from the center sills to the side sills of the car and intermediate the channel bolster members 6 at either end of the car. An end floor plate 13 extends from the channel bolster members 6 to the end sill 14 which is attached to the draft sills by means of angle-bars 15.

A bolster cover plate 16 is disposed above, and overlapping the ends of, the floor plates and the end floor plates. The center sill cover plate 17 overlaps the rear edge of the cover plate 16 the inner edges of the floor plates 12 and extends from bolster to bolster. These several plates re perforated in con at a distance apart formity to each other and to the flanges of, the center sill, the end sill and the body bolster members. Rivets pass through the said perforations and securely fasten the said plates and the said flanges. End wall plates 18 may be riveted to the side sills, draft sills and the end floor plate as shown in Figs. 1 and 2.

Although I have shown and described my invention in considerable detail, I do not wish to be limited to the exact construction shown and described, but may use such substitutions, modifications or equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A car underframe comprising a center sill, a draft sill and bolster members, said center sill members and draft sill members being alined at their junction, said bolster members bent at their inner ends to form splice-plates at the union of the center sill and draft sill.

2. A car underfrai'ne comprising center sills, draft sills and bolster members, said bolster members bent at their inner ends and secured to the external surfaces of the center sill and draft sill members, thereby forming splice-plates for the union of the center sills and draft sills.

3. A car underframe comprising a center sill, a draft sill and bolster members, a splice-plate integral with one of the bolster members and secured to the external surfaces of the center sill and draft sill members.

4. A car underframe comprising a center sill, a draft sill and bolster members, center sill and draft sill in alinement at their junction and splice-plates each integral with .a bolster member.

5. In a car underframe, a center sill member alined with a draft sill member at their junction, a bolster member having integral splice portions secured to the external surfaces of the center sill and draftsill members.

G. In a car underframe comprising center sills, draft sills and bolster members, center sills extending through the bolster, draft sills abutting the ends of the center sills, splice-plates connecting the center sills and draft sills, each integral with a bolster member.

7. A car underframe comprising center sills, the ends thereof reduced in depth and extending through the bolster, draft sills alined and spliced to the center sills, splicing members therefor formed integral with the bolster member.

8. A car underframe comprising center sills, the ends of which are reduced in depth and extend through the bolster, draft sills alined with and spliced to the center sills, splicing members therefor formed integral with the bolster member, and cover plates for the top and the bottom of the bolster.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.

RALPH V. SAGE.
